There are many methods for modeling species distribution in the landscape. In this chapter, the authors elaborate on the concepts of species modeling and present three popular techniques to generate species distribution: cartographic overlay, logistic multiple regression and maximum entropy (MAXENT). The cartographic overlay method is relevant to generate a habitat suitability index. Logistic m...

To determine if paced cycle length-dependent changes in the QRS duration correlate with the change in ventricular tachycardia (VT) cycle length after procainamide, we measured the QRS duration during sinus rhythm and during right ventricular pacing before and after procainamide (mean concentration, 9.9 micrograms/ml) in 18 patients with morphologically identical VT induced at both study periods...

Alum used for poultry houses is sold under the commercial name of “Al+ Clear” in either liquid or dry form. Alum should not be confused with other litter treatment chemicals such as “PLT” (poultry litter treatment), as PLT is comprised mainly of sodium bisulfate (NaHSO4). Although PLT is effective at reducing ammonia levels, pathogens in house, energy costs, and potentially increasing forage yi...

From 1995 to 1998, more than 90 percent of mid-range IPOs were charged underwriter fees, or spreads, of exactly seven percent, even though evidence suggests that economies of scale in the size of the offering should allow for lower fees. Chen and Ritter (2000) offer collusion as a possible explanation based on empirical analysis and observation. Alternatively, we investigate whether the spreads...

background: ca-125 is a glycoprotein and its origin is uncertain during pregnancy. it arises during the first trimester and return to a non-pregnancy range in late pregnancy. objective: the aim of this study was to compare ca-125 level in threatened abortion and normal pregnancy less than 20 weeks of pregnancy. materials and methods: this was a prospective case study carried out on 50 healthy p...

Competency-based education (CBE) in dental hygiene education is intended to measure learned skills that prepare students to independently provide services for the public. A variety of standardized clinical assessment techniques (SCATs) are available to substantiate the competence of health care professionals, including, but not limited to, objective structured clinical examinations (OSCEs), tri...

This research aims to establish the effects of length activated carbon-based medium on exhaust gas emission and evaluate engine's corresponding performance. The method utilizes peat soil as source carbon. is dried then passed through a 30-mesh sieve. It further heated 400°C for an hour, soaked in 25-percent H2SO4 solution, maintained at 120°C oven. resulting carbon packed into absorbent tube wi...
